Mrs G.G. Gerbing Azalea vs George Lindley Taber Azalea

Pick Mrs G.G. Gerbing if you want white flowers and George Lindley Taber if you want pink-and-white bicolor, because the two grow almost identically. Gerbing is a color sport of Taber, so the choice is about how the bloom looks in your bed, not about which plant is harder to keep alive.

That said, a wrong pick still costs you. A bicolor planted beside the wrong neighbors looks busy for the few weeks it blooms, and you live with the dark evergreen leaves the rest of the year. Both also yellow fast in soil that isn't acidic, which is the problem customers call us about most. Read on for the season-by-season differences in bloom, size, shade, soil and winter hardiness, and for who we'd give each plant to.

Parent and Sport: How Mrs G.G. Gerbing Relates to Taber

Before you compare the two, it helps to know how they are related, because that explains why they grow so much alike.

George Lindley Taber is the parent cultivar, a pink-and-white bicolor Southern Indica azalea that has earned respect among gardeners for decades. Mrs G.G. Gerbing is a white-flowered sport (a spontaneous genetic variation) of George Lindley Taber, found in the southern U.S. nursery trade.

A sport means Mrs G.G. Gerbing inherited most of the Taber characteristics but expressed a dramatic change in flower color. Think of it as the same plant turning white while keeping everything else intact. One of the most common questions we get is whether the white one is the weaker plant. In our rows, we see no difference in vigor.

Foliage	Dark green, evergreen, slightly hairy	Similar

Spring: Flower Color and Where Each Plant Fits

Spring is when the choice shows, because bloom color is the one real difference between Mrs G.G. Gerbing and Taber.

This is where the story really matters. George Lindley Taber delivers a classic pink-and-white bicolor flower that makes a bold spring statement. The combination reads "traditional Southern garden" to many gardeners. Mrs G.G. Gerbing goes the opposite direction with pure white blooms and occasionally a faint chartreuse or green throat blotch, creating an elegant, understated look.

The white color of Mrs G.G. Gerbing makes it exceptionally useful for blending with other colors. It won't clash with adjacent plantings the way a pink tone might. If you're designing a shade garden or a softer color palette, the white form is often the better choice. Conversely, if you want a statement plant or prefer the warmth of pink tones, George Lindley Taber's bicolor gives you more personality in a single bloom.

Both cultivars bloom mid-to-late spring (typically March-April in the Deep South, later further north in their range) with little to no noticeable fragrance.

For dates and shades in more detail, see our bloom time and flower color guide.

Landscape uses

Because the two share a size and a need for acid soil, they slot into the same places in a landscape.

Both cultivars excel in foundation plantings, mass plantings or drifts, informal hedges and screens, woodland or shade garden understory, and as specimen plants near patios. The white color of Mrs G.G. Gerbing makes it particularly valuable as a cooling element in a garden design or as a focal point that won't compete with colorful neighbors.

George Lindley Taber's bicolor works best when it's allowed to be the color star, with quieter companions in green foliage or soft purples and blues nearby.

Both pair well with camellias, ferns, hostas, dogwoods, and hydrangeas in the same acidic soil environment.

Summer: Size, Shade and Pruning Timing

By summer the shrubs have finished flowering and are setting next year's buds, so this is when size, shade and pruning decisions pay off or backfire.

How big they get

Both are large shrubs, so plan the space before you pick a color.

Southern Indica hybrids as a group reach 6-12 feet tall and 6-8 feet wide, at a moderate growth rate. We have no verified figures for either cultivar alone, and since they are so closely related, we plan for the same size. Don't confuse them with true Rhododendron indicum, a much smaller and slower shrub of 2-3 feet.

Both are substantial shrubs, not dwarf selections. If you need something under 4 feet, these aren't your answer. If you're looking for a strong backbone plant for a foundation bed, mixed border, or informal hedge, both cultivars fit perfectly.

Shade, water and pruning

Afternoon shade, steady moisture and a well-timed cut do more for these shrubs than any product we sell.

Azaleas prefer cool, partially shaded sites, and afternoon shade matters most from midsummer on. Scorched, bleached leaves on the sunny side of the plant usually mean too much western sun, not a disease.

Both need partial shade to filtered sun, ideally with morning sun and afternoon shade. They're moderate and consistent in water needs but do not tolerate standing water or prolonged drought once established. In the first year after planting, consistent moisture is critical.

Pruning is best done immediately after spring bloom finishes, as flower buds for next year set in summer. Light shaping is fine, but avoid heavy pruning in fall or winter, which removes next year's flowers.

One piece of common advice we don't follow is the tidy late-winter cutback. It removes the buds, and the shrub flowers little that spring. Cut right after bloom, as Clemson also advises, and see our pruning guide for how far back to go.

Pests and pets

The two cultivars share the same pest list and the same cautions around animals.

Both attract bees and hummingbirds, and the ASPCA lists the genus as toxic to dogs, cats and horses, so keep them away from pets that chew. The risk to people is low. Both are also prone to azalea lace bug, spider mites, scale, petal blight, root rot and powdery mildew.

If leaves look pale and stippled on top with dark specks underneath, look for lace bugs before you reach for fertilizer.

Fall: Soil, Planting and Yellow Leaves

Fall is the season we like for planting in the South, and it is the best time to get the soil right before the roots settle in.

Here's where the similarity really shows: both are Southern Indica hybrids, so they share the same fundamental needs. They demand moist, well-drained, humus-rich soil with a pH between 4.5 and 6.0 (acidic). Alkaline or neutral soils often lead to chlorosis (yellowing leaves) and poor performance.

When a customer calls about yellow leaves, we ask where the yellow is. Green veins on yellow leaves point to high pH and iron the roots can't take up. Leaves that are yellow all over, wilting, with a soft brown root collar, point to wet feet and root rot.

Common advice says to pile fertilizer on a yellow azalea. We don't, because feeding won't fix a pH or drainage problem. Test the soil, lower the pH if needed, and set the root ball an inch or two above grade so water drains away from the crown.

Winter: Hardiness for Mrs G.G. Gerbing and Taber

Winter decides whether either shrub is a safe buy for your yard, so check your zone before you check the flower color.

The hybrid group is listed for zones 6a through 9b, but we don't plant to the edges of that range. We call zones 8 and 9 reliable for Mrs G.G. Gerbing. George Lindley Taber, as the parent, should match, though you should confirm with a local nursery.

In zone 7b, choose a sheltered, slightly warmer spot and keep it out of harsh winter wind. Our zone guide covers the marginal cases in detail. Further south in zone 9, both tolerate more sun in humid climates, but afternoon shade still helps. Deer also browse them hard when other food runs short.

Which One We'd Choose, and for Whom

For most customers we'd choose Mrs G.G. Gerbing, because white fits nearly every border. Taber wins when you want pink tones to be the show, and the lists below explain each side.

Which smells better?	Neither. Both have little to no noticeable fragrance. Choose for color and form, not scent.
Which is better for foundation planting?	Both work. Mrs G.G. Gerbing's white blends seamlessly. George Lindley Taber makes a bolder statement. Pick by color preference.
Can I grow both?	Yes. They like identical conditions. A white (Gerbing) and bicolor (Taber) pair makes a sophisticated spring contrast.
Where do I buy them?	Most large nurseries carry Southern Indica hybrids. Mrs G.G. Gerbing is usually sold in quart, #1, or #3 containers as a nursery-grown plant. Verify George Lindley Taber availability in your region.

White or Bicolor: Our Bottom Line on Mrs G.G. Gerbing

Mrs G.G. Gerbing and Taber are the same shrub in two outfits, so choose on bloom color and then give both acid soil, afternoon shade and a cut right after flowering. If leaves yellow, read the pattern before you feed, and if winters in your zone dip toward 7b, give either one shelter.

Before a plant leaves us, our growers check that the roots are white and firm, the leaves are evenly green with no lace bug stippling, and the root ball has never sat wet. We raise every azalea on our own farms, and we grow and sell top-quality shrubs, so that check is how we stand behind them.
