Darwin Perennials Agastache Little Adder

The primary difference is its size. 'Little Adder' is specifically bred for a compact, mounded habit that stays around 1.5 feet tall, making it much easier to tuck into the front or middle of a garden border compared to taller, leggier varieties.

Yes, this variety is notably resistant to deer and rabbit browsing. While no plant is entirely immune to hungry wildlife, 'Little Adder' is a reliable choice for gardens where these pests are a common concern.

You can expect a long, vibrant flowering season. It typically blooms from early summer through early autumn, specifically June through September, providing consistent color and pollinator activity.

It is quite adaptable to average garden soils. The most important requirement is that the soil must be well-drained, as Agastache does not like to sit in waterlogged conditions.

Once established, it shows good tolerance for short-term drought. However, for the best performance and continuous blooming, it prefers average watering rather than extreme neglect.

Because it is a shorter-lived perennial, it benefits from occasional division. Dividing the plant every few years helps maintain its vigor and keeps it blooming reliably throughout the season.
