センペルビウム「ロータート」は、非常に魅力的な、きゅっと集まって育つ品種です。当初は緑色の子株が現れ、中心部のロゼットの紫色と美しく対比しますが、やがてこれらも同じ色合いになり、見事な小さな株を作り出します。毛羽立ちは、多肉植物を低温や強い日差しから守るのに役立ち、山岳地帯を通過する雲の霧を捕らえることもできます。

On Arrival

センペルビウム 'ロスハート' is sent bare-root. Unpack it promptly and either pot it up or plant it out into free-draining, gritty compost or soil, spreading the roots naturally and keeping the crown level with the surface (never buried).

Settle it in with one light watering, then let all excess moisture drain away. A bright, sunny, airy spot suits it best; a bare-root rosette may look a little limp at first but plumps up and roots quickly, often within a couple of weeks.

Once anchored it needs almost nothing from you. Full sun, sharp drainage and airflow matter far more than watering, and from there this tough little alpine simply gets on with spreading.

Watering

センペルビウム 'ロスハート' is extremely drought-tolerant. Water it in lightly after planting, then leave established plants to nature; in normal UK conditions rain provides all the moisture they need, and they will happily go weeks without water.

Containers dry faster than open ground, so give them an occasional soak in prolonged summer heat, directing water at the gritty compost rather than into the rosette. Always let the compost drain freely afterwards.

The single greatest risk is winter wet, not cold. Where drainage is sharp, ordinary rain is fine; it is standing water and sodden compost around the crown that cause rot. Never let the roots sit wet through autumn and winter.

Light and position

Give センペルビウム 'ロスハート' 日なた - 5時間以上の日当たり. Suitable positions include ロックガーデン、パティオ、屋外テーブルトップ、地面. Full, open sun is essential: it keeps the rosettes tight and compact and brings out the strongest 緑、赤、白 tones and reliable flowering.

In shade or under taller neighbours the rosettes stretch, pale and lose their colour, so keep the plant clear of anything that will overshadow it as the season fills out. Trim back encroaching growth rather than let it cast shade.

Good airflow matters as much as sunshine, especially in wet spells. Clear fallen leaves and debris that could trap moisture against the rosettes.

Compost and drainage

Plant センペルビウム 'ロスハート' in an airy, gritty, sharply drained mix. For containers use roughly 50% multi-purpose or loam-based compost to 50% horticultural grit or perlite, and always choose a pot with open drainage holes. These alpines actively prefer poor, lean, stony ground.

In the garden, improve heavy soil with plenty of grit and plant on a slight mound, raised bed or wall pocket where winter water drains away quickly. A mineral top-dressing of grit around the base keeps the lowest leaves off damp soil.

Do not enrich the site. Rich soil produces soft, loose growth; Sempervivums stay tightest, best-coloured and most weatherproof in moderately lean, free-draining conditions.

Feeding

センペルビウム 'ロスハート' needs very little feeding, and lean conditions give the best colour and form. Plants in open ground and fresh gritty compost generally need no fertiliser at all.

If a long-established potted plant looks weak, a single dilute, balanced feed in spring is plenty. Feed only once growth is active and the compost is moist.

Avoid over-feeding. Excess nutrients force soft, lush, stretched growth that loses colour, spoils the tight rosette shape and is far more prone to winter damage.

Winter care

センペルビウム 'ロスハート' is a fully frost-hardy alpine that lives outdoors year-round; its recorded minimum is -15°C. It shrugs off hard UK frost and snow, so no heating or bringing indoors is needed, and it must not be kept warm and dark inside.

Winter care is really about keeping the roots and crown from sitting wet. Ensure drainage stays sharp, clear fallen leaves and soggy debris from around the rosettes, and if a container cannot drain freely tip it on its side or move it under an open shelter during long wet spells.

The rosettes may close up, flush deeper colour or look a little tired in the cold; this is normal and they green up and grow away again in spring.

Summer care

センペルビウム 'ロスハート' revels in summer sun and copes easily with ordinary drought once established. Water only newly planted rosettes through extended dry spells, and give pots the occasional soak in real heat.

Keep neighbouring plants and weeds cut back so nothing shades or smothers the colony, and maintain a clear layer of grit around the crown. Strong light through summer builds the best colour.

Mature rosettes may send up a flower spike; this changes their shape and is part of the plant's natural cycle. Remove spent stems once dried, unless you want to collect seed.

Repotting

Repot or divide センペルビウム 'ロスハート' in spring when the colony fills its container, the compost has broken down or the mat becomes congested. There is no urgency; Sempervivums are happy quite crowded.

Lift the clump, separate healthy rosettes with their own roots and replant at the same depth in fresh, gritty compost, discarding any dead or flowered rosettes. Firm in gently around the base.

Water once to settle the roots, then let the compost drain. Newly divided plants establish quickly in a bright, airy spot.

Common problems

The most alarming-looking event is harmless: a rosette flowers, then dies. This is the plant's natural monocarpic cycle, not a disease, and the センペルビウム 'ロスハート' colony is not failing. Remove the dry flowered rosette and let the offsets close the space.

The one genuine killer is rot from winter wet or poor drainage. Soft, browning or collapsing crowns mean trapped moisture; sharpen the drainage, clear wet debris and make sure nothing smothers the rosettes.

Pale, loose, stretched growth means too little sun or too much feeding. Move the plant into full sun, stop feeding, and let tight, well-coloured new rosettes replace it.
