Matrix Asiatic Lily

Matrix is an Asiatic lily selected for vivid summer flowers on sturdy, upright stems. The bowl-shaped blooms face upward and outward, with red-to-orange petals, darker speckles and an orange throat; the exact balance of these tones varies between published profiles. ## Garden use and siting Plant Matrix in a border or container, or grow it for cut flowers. Give it full sun or light partial shade and moist, well-drained soil. The [RHS Matrix profile](https://www.rhs.org.uk/plants/279598/lilium-matrix-ia-b-b/details) recommends sheltering the planting and keeping the base of the stem shaded while the upper growth receives sun. [SiteOne’s Matrix listing](https://www.siteone.com/en/79450b-lilium-x-matrix-asiatic-lily/p/896375) gives USDA zones 3a–8a. Mature-size listings differ: SiteOne gives 24–36 inches tall and 6–12 inches wide, while the RHS profile reports a taller maximum. Check bulb and local growing conditions when planning around nearby plants. ## Seasonal interest The flowers appear in summer. Deadheading faded blooms can keep the display tidy; leave the foliage in place until it dies back naturally so the bulb can replenish. ## Maintenance Plant bulbs in autumn at the depth recommended for the bulb size, in loose soil that drains freely. Water to keep the soil evenly moist during active growth, but avoid waterlogged conditions. A sheltered position helps protect stems and flowers. Remove faded blooms for appearance, then allow foliage to yellow before clearing it. The RHS lists no routine pruning and recommends dividing offsets after the leaves die down.
