Powis Castle is likely a hybrid (Artemisia arborescens x A. absinthium Powis Castle is a bushy, woody-based perennial […]
Volcano Mulching Harmful
Piling up mulch around trees or shrubs, called “volcano mulching”, is a bad practice and is killing them. Perhaps you’ve seen a neighbor or a professional landscaper doing it, and assumed that it must be alright. It’s not!

‘Autumn Bride’ Started A Heuchera Evolution
Autumn Bride heuchera (Heuchera villosa ‘Autumn Bride’) is blooming now. This native ground cover, aka “hairy alumroot”, displays wide lime-green foliage which is not as colorful as many new H. villosa hybrids introduced in recent years.

To Grow Crocosmia Or Not?
This South African native, also called ‘montbretia”, thrives in full sun in well-drained average garden soil.

Established plants are exceptionally summer heat and drought tolerant. Brightly colored […]
