This variety of eranthis is leafier with more lemon-colored flowers than the cilicica variety.

This is one of the earliest flowers to bloom - even before crocus and snowdrops. I look forward to the bright yellow little blossoms every year. They mean Spring is on the way.

Anything that blooms in the wake of receding sheets of ice and snow around here is very much welcome. Following are heavily quoted & paraphrased germination instructions from Norman C. Deno's Seed Germination Theory and Practice, 2nd edition:

The best way to propagate this plant from seed is to direct sow the seed as soon as it is fresh where it is intended to grow, because:

Seed dry stored either at 40*F or 70*F is dead (as is all commercially distributed seed under current practices).

Seed should be stored and/or distributed in moist paper towels either at 40*F or at 70*F, if at all.

Alternative to direct sowing, "...seeds are placed in moist paper towels at 70*F as soon as they are ripe in May. After 3 months at 70*F, the s... read more

I love the Winter Aconite. It's pretty and cheerful, and is literally an early flower.

I don't care how invasive this plant becomes. I'm just glad to have anything blooming this time of year. I'm hoping it colonizes my small patch of lawn.

If it were not for its early blooming season, I would eradicate this from our garden. It is extremely agressive and has spread into large colonies in just a few years.

I plan to weed out much of it each year after it blooms to reduce seed production in an attempt to control its spread. Seeds appear to germinate readily, increasing the size of the colony.

Best in large groups, due to ground-hugging nature of foliage and blossoms.
