Marrubium supinum

Horehound has crinkled, scalloped edged, downy foliage, and all through Summer and into Autumn spires of lilac-coloured flowers that are attractive to bees.


Flowering

From Early Summer TO Mid Autumn

Hermaphrodite (having both male and female ) flowers are positioned in the leaf-axels - nettle-like, from early Summer to early / mid Autumn.. Flowers appear anywhere between April and October, depending on the location. The flowers are pollinated by bees

 

Propagating by seed

From Early Spring TO Mid Spring

Sow seeds in a pot or tray filled with proprietary seed-sowing compost, or a 50/50 mix of multi-purpose compost and perlite or coarse grit. Sow large seeds with space between the seeds, and sow small seeds thinly, and cover the seeds with a thin layer of sieved compost (unless it is a type of seed that needs light to germinate). Water gently with a fine rose on the watering-can, allowing excess water to drain away.

 

Planting

From Mid Spring TO Late Spring

When seedlings are big enough to handle, and after last frosts, plant out into a sunny site (horehound cannot grow in shade,) in moist but free-draining soil. Water to establish the plant
