Descriptif de la plante
This hop-headed barleria is very ornamental indeed: its leaves have a pinkish-red veining to great effect, and its pretty yellow flowers emerge from dense, highly original spikes. Its leaves are used in decoctions to soothe snake bites and insect stings.
For the record, its species name "lupulina" comes from the Latin "lupus" meaning wolf. Its spikes are reminiscent of hops, a liana that literally clings to its supports, which can be trees, and is suspected of sucking their sap, as a wolf does with the blood of its prey...…
But don't worry, you can adopt a Barleria lupulina in complete safety - it won't turn into a vampire!
Conseils de culture
When you receive your plant, repot it in a pot slightly larger than the bucket, which must be well pierced. Avoid pot covers which prevent residual water from draining away and encourage fungal diseases. Choose a fine potting soil, ideally with added perlite or sand to lighten the substrate (do not use garden soil or acidic soil such as heather). Then plan two repottings per year (spring and autumn), gradually increasing the size of the pot and adapting it to the size of the root network (the roots must have room, but not too much as the plant must be able to dry out its substrate between waterings). This avoids having to add fertilizer, which always risks burning the fragile roots of the plants and making the plant wither as soon as the fertilizer is stopped.
Moderate watering: watering should be copious (the whole root ball should be wet), but wait until the substrate has dried deeply before watering again (you can stick your finger in the soil: as long as you feel moisture, do not water). Your plant will recover better from a lack of water than from an excess of water. Always water at the base of the plant, and do not mist it, because stagnant water in the armpit of the leaves favors cryptogamic diseases. If your atmosphere is too dry, put bowls of water nearby (above radiators for example), so that evaporation humidifies the air.
For an indoor planting
Your plant is best taken out in summer, full sun is perfect for it. It should be brought indoors in winter, and ideally placed in a warm and luminous place, like in a veranda or behind a window. It fears excessive humidity when temperatures are low, so avoid cold rooms. Attention: do not take it out and bring it in all the time, it should be taken out in good weather, then brought in when the cold weather arrives, because plants adapt their foliage to their environment, which should not constantly change. It often happens that plants lose their foliage when they are taken out and/or put in, don't worry, your plant will adapt and will emit its new foliage accordingly.
For an outdoor planting
This plant is not frost and/or cold resistant and should not be planted outside except in limited parts of Southern Europe.
This plant can not be pruned If you feel that it is becoming too bulky, you can limit its growth by continuing to repot it and change its substrate but without increasing the size of the pot. If the root network becomes too important, do not hesitate to prune the roots.
Our plants are grown naturally, without chemical fertilizers, so we advise you to repot them regularly (twice a year) rather than adding fertilizer.
In case of pest attack
If your plants are under attack by aphids or other pests, the best way to control them is by hand. Change their soil, remove as many undesirables as possible by hand and then shower your plants with a strong stream of water to eliminate any eggs that may be present. Spray them (insist on the underside of the leaves) with liquid black soap diluted in water. Repeat the operation several times at a few days interval. Take them outside in good weather, rain, sun and wind will kill most of the aggressors!
