Aconitum arendsii

Trial: Perennial

Years Trialed: 2001, 2002

Good Qualities:

Year 1:

The flower size was good (despite the fact that they struggled) and they have a nice fragrance; Excellent fall color - stiff stems; Nice tall, dark blue flowers, pest free.

Year 2:

Excellent fall color, stiff stems, long vase life, can take multiple frost and still be cuttable.

Problems:

Year 1:

This was rotten on arrival - apparently is a poor shipper; I'm not sure that these will grow well enough here to be used as a cut flower (zone 7a); Blooms very late (zone 6) B Corms do not store well - must be shipped soon after digging; None of the roots came up B They were planted in perfect conditions immediately, upon arrival; Blooms over very short period, 3-4 weeks, July-August B Completely dormant in winter time so it can get lost.

Year 2:

Never flowered, died in our climate (Zone 8a); Bulbs rotten when arrived 2001, too bad; Too much west coast production - market flooded.

Comments:

Year 1:

We had a cooler than normal summer and I had them in about 50% shade B They survived the summer B I didn't think that they would live here, I'm still not sure that they will; Similar to other aconitum and to A. carmichaelii; Plants (tubers) evaluated here are from earlier planting of purchased material.

Year 2:

Similar to other aconitum, this is the fall aconitum; Very vigorous - must be dug and divided every 2-3 years, corms store poorly, replant quickly (Zone 6).
