Arum


QUICK REFERENCE PLANTING GUIDE

1. Light/Sun Exposure - Full to partial sun.

2. USDA Hardiness Zones - As indicated below.

  • 'VooDoo' - 7 to 9
  • 'Lords & Ladies' (Italicum) - 4 to 9

Both varieties require winter protection in northern zones.

3. Planting Distance - As indicated below.

  • 'VooDoo' - 2 to 3 feet apart
  • 'Lords & Ladies' (Italicum) - 1 to 2 feet apart

4. Mature Height/Spread - As indicated below.

  • 'VooDoo' - 4 to 6 feet
  • 'Lords & Ladies' (Italicum) - 14 to 18 inches

Both varieties will reach their mature height the first year.

5. Bloom Time - As indicated below.

  • 'VooDoo' - Mid-summer
  • 'Lords & Ladies' (Italicum) - Early to mid-spring

6. Planting Instructions - Dig a hole twice as deep and twice as wide as each dormant bulb. When dug, the hole should be big enough to allow the dormant bulb to be covered with 1 inch of soil.  Place bulb in hole and cover with soil, firming the soil with your fingers. Water thoroughly.

Your Arums have been shipped to you as dormant bulbs for the proper planting time for your area. They will begin underground root development as soon as they are planted. Plant as soon as possible after they arrive.

VARIETAL INFORMATION

The Dragon or Voodoo Arum can grow 4-6 feet tall. Maroon blooms in June or July are followed by scarlet red berries that last into the fall. The maroon summer blooms include a two foot plus leathery crimson-red spathe with wavy edges and a very dark black-red spadix. The leaves and stems are attractively mottled in purple. This striking plant likes a sunny spot.

Lords & Ladies Arum (Italicum) has something different for each season! Its large, ornamental, arrow-shaped leaves appear in the fall and become marbled and silver- veined. They remain on the plant during the winter. In the spring the plant produces flowers, similar to Jack-in-the-Pulpit, with its odd hooded blooms. In the summer it dies down but then surprises us again with interesting spikes of red/orange berries.

SOIL PREPARATION

Although these plants will perform well in average garden soils of all types, we recommend having your soil tested periodically by the local County Extension Office.  These tests can determine if the soil needs any amendments to enhance your plants' growth and performance.  See below for our recommended practice to improve your soil without any additional testing:

1.  Spade or till the soil to a depth of 12-18 inches.

2.  To provide nutrients and improve drainage, add organic matter to your soil by mixing in a 2 to 4 inch layer of dehydrated manure, garden compost, shredded leaves, and/or peat moss.

3.  After active growth begins, periodically feed with Cottage Farms' water soluble Carefree Bud-N-Flower Booster. Plants in containers need more frequent watering and feeding, especially when in active growth and bloom.

CONTINUING CARE

Water - Your plants require 1" of rainfall (or equivalent watering) each week when planted in the ground.  Do not allow plants in containers to dry out.  In a container that is exposed to full sun, water it well at least once every other day, and possibly every day, during periods of intense summer heat.  You may wish to temporarily move containerized plants to an area where they are shielded from the hot summer sun (i.e.,in the shade of a tree, on a porch near an overhang).

Mulching - Apply a 2-4 inch layer of shredded bark, compost or other organic mulch around your plants to promote moisture retention, maintain even soil temperatures, and to discourage weed growth.

Weeding - Keep the area around your plants free of weeds. Weeds compete with all plants for food, water and light. Walk around the garden periodically and pull weeds, including the roots, as soon as you see them.

Grooming - Clip off dead or unsightly growth to maintain attractive form and shape.  Deadhead or remove flowers when blooms have faded, leaving as much foliage as possible.  As long as the foliage remains green it will gather sunlight and transmit energy into the root system for the following growing season.

Feeding - Feed your plants once every 2-3 weeks during the growing season with a water-soluble fertilizer such as Cottage Farms' Carefree Bud-N-Flower Booster. Discontinue feeding after September 1st so your plants can harden off for winter dormancy. Resume fertilizing when new growth appears in the spring.

Winterizing - When freezing weather threatens, apply a winter mulch of evergreen boughs, straw, or leaves to in-ground plantings to prevent lifting of the plant's roots during alternating periods of freezing and thawing.

For container plantings, you can move the containers to the south side of your homes foundation and mulch for the winter. Such warm locations can actually increase the hardiness factor for these plants sometimes by two planting zones. You can also bury or plant either the plant itself or the entire container in the garden and mulch after the ground has frozen. Containerized plants may also be moved into an unheated area such as a garage or basement. If moved to a protected area be sure to give them a light watering once every 7 to 10 days.

As soon as the weather warms up in the spring remove any mulch from in-ground plantings. At the same time be sure to clean up the garden and to remove any dead or damaged parts on any plants. This is also the right time to bring any containerized plant back out into the garden sunlight where it will immediately begin to repeat its yearly garden performance.  

CAUTION: Not all plant material is edible. Though most plants are harmless, some contain toxic substances which can cause headaches, nausea, dizziness, or other discomforts. As a general rule, only known food products should be eaten. In case of ingestion, please contact your local poison control center at once and advise them of the plant ingested. Keep out of reach of children.
