XERANTHEMUM - White Immortelle - PLANTS

Xeranthemum - White Immortelle

Plants

Sale price$9.00

A delightfully wispy, antique white paper daisy type flowers on wiry thin stems with silvery foliage. Very productive, and a favourite of the bumblebees. Dries amazingly.

We've found xeranthemum don't like wet feet, or being held in their cell trays for too long, so make sure they get planted out quickly. They have also shown promise at potentially being a hardy (or hardy-ish) annual, self seeding and happily surviving our very mild winter so far.

Please note, we have a minimum plant order of $45 (approx. 5 plants) – you can mix & match any plants to meet the minimum.

Our plant boxes can fit up to 10 plants per box.

Plant orders are shipped on Mondays (& Tuesdays).

See our Shipping Page for more info.

Xeranthemum annum

Plant Type: Annual

Ideal Location: Full Sun

Spacing: 22cm

Height: 40-60cm

Xeranthemum may potentially be hardy. It self seeded and grew over winter in one of our tunnels just fine, but that would have been a pretty mild almost frost free winter (but our tunnels aren't very insulating so it definitely would have survived a light frost).

Xeranthemum hate wet feet, so make sure not to over water them as seedlings and plant them in a very well draining spot.

If growing for cuts it would be worth sowing multiple successions so you can harvest the entire plant at once then sort through the stems vs trying to pick through their tangly stems one at a time.

Xeranthemum make fantastic dried flowers, make sure to harvest when most flowers aren't too open as older flowers may end up browning as they dry.

A Note on Hardening Off

All our plants are grown as we would grow & plant ourselves, which means we typically do not harden off (acclimatise) any of our smaller plants before planting.

Instead, after planting, we always cover all our plants with some sort of frost/mikroclima type cloth over wire low hoops. We leave this cover on till the plants are too big for the cover (usually a couple months later). We have found this extra layer of prolonged cover does away with any need to faff around hardening off plants, and the difference between any plants under these low hoops and those with zero transitionary cover is astonishing!

Prior to planting we also always give our plants a very good soak in water with a swig of seaweed solution and innoculate our plants with beneficial microorganisms. This helps alleviate stress, and start all our plants off with the best possible beginnings.

If however you don't / can't plant under some similar sort of cover, then we do definitely recommend you give your plants 5–14 days to slowly acclimatise to your less protected environment before planting out. We are reasonably mild compared to more southern growers, so easing the plants into colder climates is definitely advised.

Cloth: Polynet / Redpath
Hoops: 4mm Fencing Wire (which we cut up to fit our beds, with bolt cutters as fencing pliers are waaay too hard on our hands!)
